Letter: Allow the forest to keep recovering

Yes, there has been logging historically in the forests of the Upper Kalang, as in most accessible forested areas of our region. The harvesting operations today are highly industrialised, totally unlike earlier (largely selective) logging regimes. This will result in the removal of most forest cover in the harvest areas. This will sever the wildlife corridors that support globally significant conservation values and will mean that a weedy mess remains (dominated by lantana) and the habitat values of the existing high conservation value forests will be degraded, our rivers polluted and the carbon stored there mobilised.

These forests have nationally and globally significant conservation values that are not compatible with industrial logging regimes because the species and ecosystems here are sensitive - these values will be degraded by industrial logging and species are likely to be made locally extinct. These values have been confirmed and strengthened by recent community volunteer survey efforts. The Upper Kalang is an incredibly significant refuge for some of the most ancient and sensitive species on the planet. Leaving these forests alone and letting them regenerate from the logging of 30-50 years ago will increase the populations of the ancient, threatened and sensitive species within them and will give them a viable future. Industrial logging today will reverse these important processes of regeneration, vaporise massive volumes of carbon, change weather patterns and deprive the Kalang of its source of clean and abundant water. The science is very clear, forests make rain and hold water like a sponge, buffering against drought and the rapidly increasing temperatures that our world is experiencing.
